Storyboard设置VC的Restoration ID
- AppDelegate.swift中加入方法:
func application(_ application: UIApplication, shouldSaveApplicationState coder: NSCoder) -> Bool {
return true
}
func application(_ application: UIApplication, shouldRestoreApplicationState coder: NSCoder) -> Bool {
return true
}
- ViewController中加入方法:
override func encodeRestorableState(with coder: NSCoder) {
coder.encode(currentAlbumIndex, forKey: Constants.IndexRestorationKey)
super.encodeRestorableState(with: coder)
}
override func decodeRestorableState(with coder: NSCoder) {
super.decodeRestorableState(with: coder)
currentAlbumIndex = coder.decodeInteger(forKey: Constants.IndexRestorationKey)
showDataForAlbum(at: currentAlbumIndex)
horizontalScrollerView.reload()
}
